Description

This magnetic stir plate spins liquid culture and lab solutions from 350 to 4000 RPM with a brushless DC motor and stepless speed control. It handles up to 2000mL and comes with two magnetic stir bars, ready to use.

Stirring liquid culture breaks up mycelium and keeps it evenly suspended, so every syringe you draw is consistent. The compact 12V plate has a frosted, corrosion-resistant top that wipes clean.

How to use it

  1. Use a flat-bottomed container. Thin, flat bottoms give the best magnetic coupling.
  2. Add the stir bar first. Drop the stir bar in before you turn the plate on.
  3. Ramp up slowly. Increase speed gradually until the bar locks onto the magnetic field and spins smoothly.
  4. Use the included power plug. Other adapters can reduce performance.

How much liquid can it stir?

Up to 2000mL.

What speed range does it have?

Stepless control from 350 to 4000 RPM.

Why won’t my stir bar spin?

Use a thin, flat-bottomed container, put the bar in before turning the plate on, and raise the speed slowly so the bar can lock on.

Does it come with stir bars?

Yes, two. You can add more with our 5-piece stir rod set.
